Just been to uk.farnell.com to check for serial flash memory and almost all are Awaiting Delivery / Out of Stock / No Longer Manufactured. Is there something else that is supposed to replace the serial flash or what?
Is Dataflash going obsolete?

Not obsolete - just hard to buy at the moment.

For example, plenty of stock for this 1Mbit SPI SOIC-8: http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&itemSeq=3D91457= 986&uq=3D634218282672489576&cshift_ck=3Dnull&client_id=3D5042 OP: What size and package are you looking for?

Only Atmel (AFAIK) has it in that package. Have no idea why packages of more pins even exist. (there are more *not used* pins than used pins) Schukat also has ALL Atmel dataflashes on allocation... wierd.

Blame Apple for hogging all the electronics and Atmel for exiting the fab business.

I've just learned AT91SAM9260 and... well, Farnell never had it (in TQFP) and Schukat now wants to sell 216 pcs at once. That leaves me with TME only.. As Uwe Bonnes explained the packing issue, I was reading about M25P32.. It is promising, price almost the same, but can't be written on a page basis w/o first erasing a whole sector (!).

We got three months of Atmel chips when it was last available. Digikey had 3 to 4 thousands and all gone the next day. Should have gone for six months of supply. We won't design with any more Atmel chip until we have a year of supply.
